UPDATE...
I got a email this morning from Dave at Brenspeed and he said if my buddy wasn't able to do a "return to stock" before getting rid of the car, then the tuner will have to go back to SCT for unlocking

.
BUT he did say if my buddy can show proof that the car was totaled, that SCT may waive their fee for unlocking it

.
I still haven't heard from Bamachips.
